Beskrivelse
About the job
For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.
The Norwegian Government's hydrogen strategy emphasizes clean hydrogen as essential to reach ambitious national and international emission targets by 2050 and provides a transition strategy for an energy-rich country. Several limitations concerning the storage and long-distance transport of electrical energy can be tackled by chemically converting it in form of hydrogen. Liquefied hydrogen (LH2) is stored close to atmospheric pressure and cryogenic temperature (around -253°C) and allows increasing storage capacity of more than 100% with respect to compressed hydrogen at 70 MPa when the same storage volume is considered. The use of LH2 is particularly attractive when the storage volume is limited, and large amounts of energy are required. However, cryogenic liquefied gas storage at very low temperatures requires an effective thermal insulation and is also subject to several operative and safety challenges. LH2 contains a larger amount of energy per volume compared to compressed gaseous hydrogen. The loss of containment of LH2 storage systems in case of accident with consequent release may lead to severe consequences that must be prevented or mitigated.
As PhD Candidate, we want you to support the activities of an ongoing national research and innovation centre for hydrogen and ammonia on modelling of physical phenomena that might be generated by LH2 leakage and dispersion during different accident scenarios. You will be collaborating with internationally renowned research institutes (e.g. SINTEF) and industries. The objective of the proposed PhD research is to improve safety of LH2 storage and distribution systems by understanding the fundamental mechanisms and consequences of selected critical physical phenomena and develop analytical and numerical models to simulate those. You will perform interdisciplinary research by focussing on different subjects such as physics, thermo- and fluid dynamics, risk analysis. Specifically, your study will involve:
By focusing on these areas, your PhD aims to establish inherent safer equipment for storage and distribution of LH2, thereby reducing the risks of current technologies. You will have the chance to collect and use first-hand data from previous and ongoing relevant research projects on LH2 safety.
You will report to Associate Professor Federico Ustolin
